Purifen

Purifen Uses, Dosage, Side Effects, Food Interaction and all others data.

Purifen possesses analgesic and anti-inflammatory properties. Its mode of action, like that of other nonsteroidal anti-inflammatory agents, is not completely understood, but may be related to prostaglandin synthesis inhibition.

Like common NSAIDs, dexibuprofen is an active enantiomer of ibuprofen that suppresses the prostanoid synthesis in the inflammatory cells via inhibition of the COX-2 isoform of the arachidonic acid COX. Attenuating the synthesis of prostaglandins and thromboxanes gives the drug three major therapeutic actions. Anti-inflammatory action comes from decreased prostaglandin E2 and prostacyclin leading to decreased vasodilation and oedema that enhances vascular permeability and activity of inflammatory mediators. Decreased prostaglandin levels in the hypothalamus confers the antipyretic effect of the drug. Analgesic effect stems from decreased prostaglandin levels that sensitize the nociceptors to inflammatory mediators at sites of pain and enhance transmission from afferent pain fibers at the spinal cord

Precaution

Purifen should be used with caution in patients with active and suspected gastrointestinal bleeding and bronchial asthma. In heart failure, hypertension, renal or hepatic disease, especially during concomitant diuretic treatment, the risk of fluid retention and deterioration in renal function should be taken into account. In case of elderly patient dexibuprofen should be started with lower dose. In case of hepatic and renal dysfunction it should be started with lower dose. It should not be used in patient with severe hepatic and renal dysfunction.

Interaction

Drug interactions is noticed with concomitant use of anticoagulant, methotrexate, lithium, corticosteroids, phenytoin, thiazides and thiazide related substances, other NSAIDs and salicylates, digoxin, ciclosporin, tacrolimus, beta blockers and ACE inhibitors.

Volume of Distribution

For more information, refer to ibuprofen.

Elimination Route

The time it take to reach peak plasma concentration is 2.25-5 hours post-administration of oral tablets containing 300mg of dexibuprofen. For more information, refer to ibuprofen.

Half Life

Oral tablets containing 300mg of dexibuprofen results in 2.2-4.7 hours . For more information, refer to ibuprofen.

Clearance

For more information, refer to ibuprofen.

Elimination Route

Mainly renal excretion. For more information, refer to ibuprofen.

Pregnancy & Breastfeeding use

Pregnancy: no clinical data on exposed pregnancies are available.

Lactation: Ibuprofen is slightly excreted in human milk. Breast-feeding is possible with dexibuprofen if dosage is low and the treatment period is short.

Contraindication

Purifen is contraindicated in patients with known hypersensitivity to any ingredient of Purifen or individuals with acute rhinitis, nasal polyps, urticaria or angioneurotic oedema, gastrointestinal ulcer or bleeding.

Renal impairment patient: The starting amount must be reduced to patients with mild to moderate kidney function impairments. Purifen should not be used patients with serious kidney function impairments.

Acute Overdose

Purifen has a low acute toxicity and patients have survived after single dose as high as 54 g of racemic ibuprofen. Mild symptoms are most common including abdominal pain, nausea, vomiting, lethargy, drowsiness, headache, titinus, nystagmus and ataxia. The onset of symptoms usually occurs within 4 hours. Treatment is symptomatic and there is no specific antidote.
